Piccard, Jean, << pee KAHR or pih KAHRD, zhahn >> (1884-1963), was a noted Swiss-born aeronautical engineer and high-altitude research pioneer. In 1934, he ascended by balloon more than 57,500 feet (17,530 meters). In 1937, he made the first piloted multiple-balloon flight, using 98 balloons, each measuring 6 feet (1.8 meters) in diameter. Piccard’s wife, Jeanette, piloted many of his balloon flights. She was the first woman to ascend into the stratosphere.
